Judge people by
their bookshelf.

Every day, a new stranger's bookshelf. Can you figure out who they are just from the books they own?

How it works

01

Study the shelf

A stranger's bookshelf is revealed. Zoom in, inspect the titles, the order, the wear.

02

Make your guesses

Who is this person? Their age, profession, interests, politics — you have 2 attempts per category.

03

See the reveal

Find out who they really are. Compare your read with the crowd — and with AI.

Are you better than AI?

Every reveal shows how an AI read the same shelf. Beat the machine.

Compare with the crowd.

See what thousands of players guessed — and where they got it wrong.

What does your shelf say about you?

Submit your own bookshelf and let strangers psychoanalyze you.

Today's case is waiting.

One shelf. Two attempts. How well can you read a stranger?
